All language subtitles for 4_Course Introduction

On July 20th 1969,

one of the most phenomenal events
made its way into the history books.

When the Apollo 11 completed its
historic mission to the moon.

While the most brilliant minds helped
to make sure that the Eagle had landed,

computers also played a significant role.

The guidance system that navigated the
spacecraft was one of the earliest forms

of modern computing.

That same computer, the one that helped
America's lunar dreams become a reality

took up the space of an entire room and
had 1/10,000th the computing power of

the thing that almost every one of you
carry in your pockets today, a smartphone.

Computer hardware and software have had
such a dramatic evolution that what was

once only used to power rockets now shapes
the entire way our world functions.

Think about your day.

Did you grab a snack?

Turn on your tv?

Take a drive in your car?

Computers were along for the ride
literally, computers are everywhere.

So here's the rundown.

By the end of this course you'll
understand how computers work and

get a grasp of the building blocks of IT,
we're going to cover

the basics of how computer
hardware performs calculations and

we're going to actually build
a computer from the ground up.

Well look at how operating systems
control and interact with hardware.

We'll take a look at the internet and

get a better understanding of how
computers talk to each other.

We'll also spend time learning
about how applications and

programs tie all of this together and
let humans interact with these systems.

Finally we'll cover important lessons
on problem solving with computers and

cover the communication skills that are so

critical when interacting
with others in IT.

Whether you're looking for a job in the IT
industry or you just want to learn how

your laptop connects to the Internet,
understanding how computers

work at every level can help you in your
day to day life and in the workplace.

But first let's take a step way way
back to where it all began even before

the Apollo 11 mission touchdown.

So you can understand how and
why we use computers today.
